Use Set to Remove Array Duplicates

Problem

Removing duplicates from arrays requires nested loops or complex filter logic.

Solution

Convert array to Set (which only stores unique values) then back to array.

Benefit

One-line solution that is 50x faster than traditional approaches.

Code Example

const numbers = [1, 2, 2, 3, 3, 3, 4];

// Remove duplicates
const unique = [...new Set(numbers)];
// Result: [1, 2, 3, 4]
